Two metal-organic frameworks with infinite indium hydroxide chains connected through tetradentate carboxylate linkers
چکیده انگلیسی

Two indium-based metal-organic framework have been hydrothermally synthesized by using 1,2,4,5-benzenetetracarboxylate (pyromellitate) or 3,3′,4,4′-benzophenonetetracarboxylate as linkers. Their structures have been characterized by means of single-crystal X-ray diffraction analysis and reveal closely related networks consisting of identical infinite chains of indium-centered trans-connected octahedra, linked to each other through the tetradentate carboxylate linkers. The structure of the indium pyromellitate (MIL-60) delimits a 3D frameworks with one-dimensional 4.0 × 2.7 Å2 channels running along [001] encapsulating water. The second compound (MIL-119) is built up from the compact stacking of the 3,3′,4,4′-benzophenonetetracarboxylate molecules connected to four distinct inorganic chains. In the latter, water species are found to be trapped between two indium hydroxide chains or in terminal positions, bonded to the indium cations. Strong hydrogen interactions are observed between these types of water molecules. Both compounds do not exhibit any significant porosity.Crystal data: In2(OH)2[C10O8H2]·2H2O (MIL-60): monoclinic, C2/m, a = 7.1854(7) Å, b = 17.1940(17) Å, c = 6.5167(7) Å, β = 100.639(2)°, V = 791.27(14) Å3, Z = 2.

Two indium-based metal-organic frameworks have been hydrothermally synthesized using pyromellitic acid (MIL-60) and 3,3′,4,4′-benzophenonetetracarboxylic acid dianhydride (MIL-119). Both structures exhibit 3D network built-up from infinite straight chains of corner-sharing indium-centered octahedra, linked to each other through the tetracarboxylate ligands.Figure optionsDownload as PowerPoint slide
